AxTools CodeSmart 2003 is a pretty cool VS.NET addin that we recently got a site license for at work. I haven't really had a chance to explore all of its features yet, but after a bit of playing it looks like it could be quite useful.

In other news, Outlook 2003 uses some undocumented MAPI properties for new contact fields such as 'IM Address'. Thank goodness for OutlookSpy, and no thanks to MS for once again making it unnecessarily difficult to write code that integrates with Outlook.
